Copper

What the Ojibwe Knew About America's Lost Copper Mines

Now I wonder if maybe The Sea People had an advanced civilization living in the far north, or maybe in Doggerland / Atlantis, and they were sending ships across the Atlantic and through the Great Lakes to get this copper. That sounds kind of nuts, but if it wasn't The Sea People, then where did all the copper go?

I posted about upper Michigan copper mines before.

Chile Mine Disaster

El Teniente New Level Mine, Chile

One miner is dead and five more are missing. Aljazeera has the story. The mine is located in the Andes Mountains about 50 miles south-southeast of Santiago. More posts about copper mining here.

There is some discussion about people in the mining business and the Paguna Mine in Bougainville comes up: "The place was famous for its hugeness and infamous for political reasons."

Paguna Mine, Bougainville
The central pit is over one mile across.

Excerpted from Wikipedia:

Panguna is one of the largest copper reserves  in the world, having an estimated reserve of one billion tonnes of ore copper and twelve million ounces of gold. The site was at one time the world's largest open-pit copper/gold mine. The mine caused devastating environmental issues on the island, and the company was responsible for poisoning the entire length of the Jaba River, causing birth defects, as well as the extinction of the flying fox on the island. Dissatisfaction with the company led to an uprising in 1988, led by Francis Ona, a Panguna landowner and commander of the Bougainville Revolutionary Army. The outcome of the uprising was the Bougainville conflict, between the BRA, who sought secession from PNG, and the Papua New Guinea Defence Force. The ten-year conflict resulted in over 20,000 deaths, as well as the eventual closure of the mine on 15 May 1989, and the complete withdrawal of BCL personnel by 24 March 1990. It has remained closed to this day.

There is also an extensive backstory about Willem, one the queen's aides. His family was in Indonesia when WW2 broke out and were imprisoned by the Japanese. Their troubles didn't end when the war did, now we have Sukarno mounting a campaign for independence which meant more chaos and more trouble for, especially for white Europeans.

Giant Sinkhole in Chile

Sinkhole in Tierra Amarilla, Chile

Giant sinkhole appeared over the weekend in the Atacama Desert. There is an underground copper mine in the neighborhood that might have something to do with it. Sinkholes are just weird.

Just for grins I tried locating it on Google Maps and from the relative positions of the buildings and roads, I think I found it.

Rio Tinto Arizona Copper Mine

Inside the Resolution Copper Mine, 1.3 Miles Underground
Story in the WSJ prompted me to look into this. The temperature at the bottom of the mine shaft is 180 degrees Fahrenheit, too hot for people to survive, much less work, but they've got people down there, so I want to see what their air conditioners look like, and I want to see their electric bill.

Didn't find much about the A/C used here, but Carrier air conditioned the nearby Magma mine back in 1937:

Dr. Willlis H. Carrier, whose invention of air conditioning dates back to July 17, 1902, is shown (at center) with the machine which made large-scale air conditioning feasible - the centrifugal refrigerating machine.

A "small" piece of copper pulled out of the Adventure mine.

One hammer drill leads to another, and we find ourselves deep underground in an old copper mine in Northern Michigan. Herewith we have a condensed version of Wikipedia's story about Copper Mining in Michigan:

The western portion of the Upper Peninsula of Michigan is highly unusual among copper-mining districts, because copper is predominantly found in the form of pure copper metal (native copper) rather than the copper oxides or copper sulfides that form the copper ore at almost every other copper-mining district. The copper deposits occur in rocks associated with the Keweenawan Rift.

The miners sometimes found masses of native copper up to hundreds of tons (fissure deposits). To extract a single mass of copper, miners could spend months chiseling it into pieces small enough to hoist out of the mine. Although they were pure copper, removing the masses took a great deal of effort, and was sometimes not even profitable.

In the 1850s, mining began on stratiform native copper deposits in conglomerates and in basalt lava flows (locally called amygdaloids). Although these deposits tended to be lower-grade than the fissure deposits, they were much larger, and could be mined much more efficiently, with the ore blasted out, hoisted to the surface, and sent to stamp mills located at a different site. Amygdaloid and conglomerate mining turned out to be much more productive and profitable than fissure mining.

A number of copper mines also contained a notable amount of silver, both in native form and naturally alloyed with the copper. Halfbreed is the term for an ore sample that contains the pure copper and pure silver in the same piece of rock; it is only found in the native copper deposits of the Upper Peninsula of Michigan.

Copper mining in the Upper Peninsula boomed, and from 1845 until 1887 (when it was exceeded by Butte, Montana) the Michigan Copper Country was the nation's leading producer of copper. In most years from 1850 through 1881, Michigan produced more than three-quarters of the nation's copper, and in 1869 produced more than 95% of the country's copper.

Annual production peaked in 1916 at 266 million pounds (121,000 metric tons) of copper. By 1968 Michigan's native copper industry was essentially dead, after producing 11 billion pounds (5.0 million metric tons) of copper.

Another IMPORTANT news story that was totally unreported by the big wigs. It's taken almost two weeks to wind it's way to me. Nobody hurt is why. The mining company had monitoring equipment that warned them of impending doom and they shut down operations the day before. The size of the landslide surprised them and buried some equipment. Mine is run by the Rio Tinto company out of Australia. Mine workers were "asked" to take a leave of absence until damage is repaired. Seems to me that repairing the damage is going to be a whole lot like mining as usual, i.e. lots of digging and hauling, so I expect the worker bees will only be out of work until the dirt nerds work out a plan. This is in Utah which is Mormon country, which means this is probably a right-to-work state, which is why we haven't heard from the Union. Mormons are a little odd (to quote W.C. Fields "never trust a man who doesn't drink") but they have a number of good qualities, like being hard workers, so the mine company couldn't ask for a better location. On the other hand I expect someone to concoct a lawsuit based on not being informed of the impending doom and it's impact on the price of the company's stock.

It's a big mine. It produces 1% of the world's copper, or at least it did. Mining and agriculture are similar in that they both suffer from over-production. Farmer has a bumper crop, so does everyone else, there's a glut on the market and price of whatever it is falls through the floor and the farmer goes broke. Same thing with mining. Miner goes into mining because there is a demand for a metal. If he makes a big strike and starts producing more metal the price falls and his vision of riches vanish. So this landslide could be a blessing for the copper industry.

I was at Home Depot looking at copper pipe a couple of years ago and the guy on the floor was telling me that you could probably get more for copper pipe at the scrap yard than Home Depot was charging for it. i.e. You could make money by buying copper pipe at Home Depot and taking it across town to the scrap yard to sell it. I didn't try it, I didn't even look into it. It seemed like sacrilege to me. Besides the price difference was probably only a few cents a pound, so it would have taken a sizable cash outlay to make it a worthwhile endeavor.
